$10 million in grant funding dedicated to San Francisco's District 10 in the southern part of the city

$4 million raised for the USCF Benioff Children's Hospital ($12 million raised in the last three years)

UPDATE: This story has been corrected to reflect that the 2012 McKinsey Global Institute Study posits that there could be $1.3 trillion in potential business value from social technologies, not $1.3 billion as previously published.
